Hertz,
If you want further opinions to what people think of their Odyssey Stratos experience go to audioreview.com and check out the 131 positive reviews for this amp.
Essentially from my perspective it comes down to build quality, resale value, 20 year warranty, bloodlines from the highly respected german Symphonic Line of audio products, ability to upgrade, and Klaus Bunge - a truly class act - who is the owner.
BTW, Klaus has recently introduced a tube preamp that has perfect synergy with Odyssey amps.
